BELLEVUE, Wash. (April 26)—Burke Industries Inc.'s Engineered Polymers Group has been sold to Esterline Technologies Corp. for $38 million. The sale will reposition Burke primarily as a black rubber and vinyl products business. Esterline will merge the polymers group into subsidiary Kirkhill-T.A. Co., which will make the unit one of the top product suppliers to the aerospace industry, with sales in the more than $100 million range annually, the company said. Esterline acquired the polymers division at a bankruptcy auction held to sell off some Burke assets. Burke filed June 25 for protection from creditors under Chapter 11 of the bankruptcy code, and the sale is aimed at helping it financially restructure, concentrating on its BurkeMercer flooring, roofing and custom-mixed rubber products operation.
